Can anyone do the steps to: 4^(1+√2) * 4^(1-√2)?
The book says it's 16, but I got 16^-1
steps:
foil exponents: that comes out to 1-2 ? Should it not be ?
then, just multiply the 4's, or do you add them?

This is your problem. What should you be doing to the exponents?

You're trying to foil the exponents. That indicates that you're multiplying them. What should you be doing instead to the exponents?
